2790.10.03

One of the Lord Holders involved gets copy of the sheet, distributed by firelizard, proposes killing the firelizards to keep the information from spreading; a three-year campaign to kill firelizards succeeds in wiping out nearly all Impressed firelizards and frightens wild ones so badly that they appear to vanish completely (whers are preserved because they're ugly and anti-social and will eat anything, making it easy to create the myth that that dragons were the same, and they still make good watchdogs)
